Abstract

The invention provides an automatic control method for polyethenoxy ether production equipment. Data acquisition and control operations are carried out on the production equipment through a DCS (Distributed Control System) with a PID (Proportion Integration Differentiation) controller, and an adjusting valve on a guide tube is controlled by the automatic adjustment of the parameters of the PID controller, so that the pressure and the temperature in a reactor are stable, the problems of too many labile factors and great effect on product quality caused by the condition that the production equipment in the traditional production technology needs manual control are solved further, and the safety in the production process is ensured.

Description

technical field [0001] The invention relates to a nonionic surfactant production technology, in particular to an automatic control method for a polyoxyethylene ether production device. Background technique [0002] Polyoxyethylene ether is an important category of nonionic surfactants. Due to its good emulsification, detergency and water solubility, it can be used as penetrant, detergent, solubilizer, dispersant, antistatic agent, emulsifier It is widely used in industrial cleaning and emulsification and dispersion. The polyoxyethylene ether can also be used as a leveling agent in the printing and dyeing industry. [0003] In the existing technology, the production process of the polyoxyethylene ether mainly goes through the following steps, that is, nitrogen replacement of the reactor, vacuum dehydration of the still material, preparation of raw materials for production, heating of the reactor, cyclic reaction, neutralization and cooling, and release In the traditional pro...
